- the groove 72 is frame-shaped and is positioned outside the outer peripheral edges of the catalyst layers 32 and 33, so that the catalyst layers 32 and 33 are not directly sucked, and are temporarily separated from the catalyst layer. Even if the catalyst particles are sucked, the polymer electrolyte membrane 30 is not adsorbed by the suction holes as compared with a mode using a porous substrate (adsorption holes) that may cause clogging in many suction holes. Occurrence is suppressed, and a reduction in production efficiency is prevented. Therefore, it is possible to provide a fuel cell electrolyte membrane gripping device capable of exhibiting good production efficiency.
- suction by the groove portion 72 is preferable in that production efficiency can be improved because release of the suction pressure proceeds instantaneously as compared to suction through a porous substrate having a large number of suction holes. Further, even if contamination occurs by sucking fine particles floating in the atmosphere or fine particles adhering to the polymer electrolyte membrane 30, occurrence of clogging is similarly suppressed.

- the groove part 72 Since the groove part 72 is frame-shaped, the places where clogging is likely to occur are the bent parts 74B and 74D. However, when one of the bent portions 74B and 74D is clogged, the other flow path of the bent portions 74B and 74D functions as a detour, so that adsorption failure (gripping failure) of the polymer electrolyte membrane 30 is suppressed. In addition, when clogging occurs in both of the bent portions 74B and 74D, the differential pressure gauges 91 and 92 can be detected early and quickly.
- a pressure detection device corresponding to the number of suction holes is required to detect clogging in units of suction holes. If the size of the molecular electrolyte membrane 30 is taken into consideration, the installation is impossible, and even if it is installed, the apparatus becomes complicated and the maintenance management becomes complicated. Further, when clogging of a large number of suction holes is detected at once by the pressure detection device provided in the upstream portion of the manifold, there is a possibility that partial clogging cannot be detected appropriately.
- the air suction line according to the present embodiment is configured by the groove portion 72, and partial blockage is unlikely to occur, and an abnormality of the groove portion 72 is caused by the minimum necessary number, that is, two pressure detection devices.

- the material that transmits light is, for example, an acrylic resin.

Therefore, for example, by visually observing the state (adsorption state) of the outer peripheral edge 31 of the polymer electrolyte membrane 30, the clogged portion can be easily identified. Further, for example, when the outer peripheral edge 31 of the polymer electrolyte membrane 30 is placed on the frame-shaped gasket 40 (45), the polymer electrolyte membrane 30, the catalyst layers 32 and 33, and the gasket 40 (45) are visually observed.

- the concave portion 76 may be provided with a through-hole 76A in order to allow the atmosphere to escape when the polymer electrolyte membrane 30 of the support body 65, which is a holding jig, is brought close to the gasket.
- the manifold 86 is preferably provided so as not to interfere with the recess 76.
- FIG. 11 is a bottom view for explaining the third modification according to the embodiment of the present invention.
- the bent portions 74A to 74D of the groove portion 72 are not limited to a substantially right-angled shape, and may be a curved surface shape that is gently bent. In this case, the air flow in the bent portions 74A to 74D becomes smooth, and the resistance during air suction is reduced.
- FIG. 12 is a side view for explaining the modified example 4 according to the embodiment of the present invention.
- the electrolyte membrane 30 is not limited to a form of being supported downward, and the electrolyte membrane 30 is disposed (placed) on the flat portion 70 of the fixed support 65A as in the gripping device 60A shown in FIG. ) Is also possible.

It is positioned so as to be laminated on the outer peripheral edge 31 of the electrolyte membrane 30.
- the electrolyte membrane is adsorbed by the groove portion disposed in the flat portion of the support, and thus wrinkles are prevented from occurring in the polymer electrolyte membrane. Furthermore, since the groove is frame-shaped and aligned outside the outer peripheral edge of the catalyst layer, the catalyst layer is not directly sucked, the occurrence of clogging is suppressed, and the reduction in production efficiency is suppressed. I can do it. Therefore, it is possible to provide a fuel cell electrolyte membrane gripping device capable of exhibiting good production efficiency.
- the groove is frame-shaped, the manifold (air suction part) is located at the bent part of the groove, so the resistance during air suction is reduced and the pressure fluctuation when adsorbing the polymer electrolyte membrane is reduced. Thus, the generation of wrinkles in the polymer electrolyte membrane is further suppressed.
- the support When the support is formed from a material that transmits light, the state of the groove, the polymer electrolyte membrane, and the catalyst layer can be detected optically. Therefore, for example, the clogged portion can be easily identified by visually observing the state of the outer periphery of the polymer electrolyte membrane (adsorption state). Further, for example, when the outer periphery of the polymer electrolyte membrane is placed on a frame-shaped gasket, the positions of the polymer electrolyte membrane, the catalyst layer, and the gasket can be confirmed by visual observation. Reliable positioning is unnecessary and reliability is improved. Furthermore, for example, since the position can be confirmed using an infrared sensor, it is easy to automate equipment (use as an element of production equipment) by work of a robot or the like.
